Are you a FTM!?

I'm so tired of people asking this every time I say something about my kid. His daycare teacher wasn't feeding him enough, and tried to say he refused his bottles. The parent contact dismissed me saying he's never had eating issues for anyone else bc he got really sick a week later and won't eat much at all. Because why would his mother know his eating habits. we pulled him out. But now that he's sick and all the DRs and nurses are dismissing my concerns bc I'm a FTM. Every time I get "is this your first?" What does that have to do with me telling you eating is causing him to scream out in pain!? I get that he has a stomach virus, and you can't treat it, but I'm telling you my son won't eat because it's too painful please run some tests to make sure nothing else is wrong. Like his doctor is concerned enough they sent us to the ER why are you questioning why I'm here. And god forbid if my MIL tells me one more time "wow I can't believe how spit up doesn't bother you." Or "Wow you've adjusted so quickly" said in the most condescending way bc she can't stand that I'm not failing as a mother and don't need her to come rescue me. And my mom who knows I've worked with babies and toddlers forever "wow look at you just holding him in one arm and making his bottle at the same time." It's like everyone thinks us FTMs can't do anything at all. We grow and adjust, and learn. We know our babies better than anyone, and are not hysterical bc we are passionate about their care. No one is perfect at this parenting thing, but we aren't any less because this is our first.
